Open Market Value (OMV) - How Singapore Customs Assesses Your Car

The Open Market Value is the foundation of Singapore's car tax system. This Customs-assessed value determines your ARF, PARF potential, and significantly impacts the total price you pay for a car.

Last updated: 11 April 2026

What is OMV?

The Open Market Value (OMV) is the price of a vehicle before any Singapore-specific taxes are applied. It's assessed by Singapore Customs and represents what the car would cost in a free market without duties or taxes.

OMV is crucial because it determines your ARF (Additional Registration Fee), which in turn affects your PARF rebate when you eventually deregister.

What's Included in OMV?

Singapore Customs includes the following in the OMV assessment:

Included in OMV

  • Purchase price of the vehicle
  • Freight and insurance costs (CIF)
  • All accessories and modifications
  • Commission paid to buying agents
  • Royalties and licence fees

Not Included in OMV

  • Singapore duties and taxes (ARF, COE, GST)
  • Registration fees
  • Dealer markup and profit margin
  • Extended warranties (if optional)

How is OMV Determined?

Singapore Customs uses several methods:

1. Transaction Value Method

The actual price paid for the vehicle, adjusted for:

  • Currency exchange rates
  • Transport costs to Singapore
  • Insurance

This is the most common method for new cars imported by authorised dealers.

2. Comparable Sales Method

For parallel imports or used vehicles, Customs may reference similar transactions:

  • Same make and model
  • Similar specifications
  • Recent import records

3. Residual Method

When other methods aren't applicable, Customs determines value based on:

  • Manufacturing costs
  • Typical profit margins
  • Market research

OMV for Different Import Types

Authorised Dealer (AD) Cars

  • OMV is typically well-documented
  • Based on official invoices from manufacturers
  • Generally consistent across same models

Parallel Import (PI) Cars

  • OMV may vary between importers
  • Can sometimes be lower due to sourcing from different markets
  • Subject to more scrutiny from Customs

Used/Second-hand Imports

  • OMV assessed based on current market value
  • Depreciation factors may apply
  • Can vary significantly based on condition and mileage

OMV Impact on Total Car Cost

Let's see how OMV cascades through the cost structure:

Example: Car with $30,000 OMV

ComponentCalculationAmount
OMVBase value$30,000
ARF100% of first $20k + 140% of $10k$34,000
Excise Duty20% of OMV$6,000
GST9% of (OMV + Excise)$3,240
Subtotal (before COE)$73,240
COE (Category A, example)Market rate~$100,000
Total~$173,240

A $30,000 car becomes over $170,000 after taxes and COE. The OMV is just the starting point!

Strategies for Lower OMV

1. Choose Base Models

Higher trim levels with more features have higher OMV:

  • Navigation systems
  • Premium audio
  • Larger wheels
  • Performance packages

Each adds to the OMV and thus to your ARF.

2. Consider Different Variants

The same car from different markets may have different OMV:

  • Japan-spec vs Europe-spec
  • Regional variants with different equipment

3. Understand What's "Optional"

Factory options increase OMV. Dealer-installed accessories (fitted in Singapore) typically don't.

OMV has been affected by several factors:

FactorImpact on OMV
Electric vehiclesHigher due to battery costs
Supply chain issuesIncreased during chip shortage
Currency fluctuationsEUR/USD rates affect European cars
Advanced techMore ADAS features = higher OMV

Checking a Car's OMV

Before Purchase

  • Ask the dealer for the OMV
  • Compare with similar models
  • Check if it seems reasonable for the variant

For Registered Vehicles

  • Check vehicle registration documents
  • Query via OneMotoring
  • Request from LTA if needed

OMV for EVs

Electric vehicles typically have higher OMV than comparable ICE cars because:

  • Battery packs are expensive
  • EV-specific components add cost
  • Advanced power electronics

However, government incentives (ARF rebates, road tax exemptions) help offset the higher OMV.

Frequently Asked Questions

Can I dispute the OMV?

Yes, you can appeal to Singapore Customs if you believe the assessment is incorrect. You'll need supporting documentation.

Does OMV include shipping costs?

Yes, OMV is based on CIF (Cost, Insurance, Freight) value: the landed cost before Singapore taxes.

Why is OMV different for same model?

Variants, options, import source, and assessment timing can all cause OMV differences for the same model.

Is OMV the same as the "paper value"?

Not exactly. Paper value for loans/insurance may differ from OMV as it includes other factors.

  • ARF: Calculated from OMV
  • PARF: Indirectly based on OMV via ARF
  • COE: Separate from OMV-based taxes
